ABSTRACT
This award represents a small planning grant for a potential future field experiment for the study of hail. The In-Situ Collaborative Experiment for the Collection of Hail in the Plains (ICECHIP) study would make use of a host of instrumentation to study hail processes in thunderstorms in the Great Plains and Front Range of the Rocky Mountains, the US locations that most commonly experience hail. The project would engage with stakeholders such as the insurance industry and operational weather forecasters to ensure broad societal impact. Significant student participation would ensure the training and education of the next generation of scientists.
The ICECHIP field campaign would make use of research aircraft, a set of ground-based radars, unmanned aerial systems, surface and upper-air instrumentation, and ground observations of hail. The research team has identified 5 major science themes that they plan to address: 1) improve understanding of hailstone development, in storm characteristics, and fall behavior; 2) examine in-storm hail trajectory and convective updraft relationships; 3) assess the impact of differing environmental thermodynamic and kinetic regimes and geographic location on hail processes and predictability; 4) summarize surface properties of hailstones and associated impacts; 5) characterize hailstone physical properties and their relationship to radar observations.
This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
PROJECT OUTCOMES REPORT
Disclaimer
This Project Outcomes Report for the General Public is displayed verbatim as submitted by the Principal Investigator (PI) for this award. Any opinions, findings, and conclusions or recommendations expressed in this Report are those of the PI and do not necessarily reflect the views of the National Science Foundation; NSF has not approved or endorsed its content.
The purpose of this preliminary grant was to assemble a full proposal for the In-situ Collaborative Experiment for the Collection of Hail In the Plains (ICECHIP) field campaign. ICECHIP would occur over a two-year period, with two successive deployments to capture climatological peaks of different types of hail. The first year would take place with a focus on the Colorado and Wyoming Front Range, and the second year would be fully mobile over the south-central Great Plains. Five specific science themes would be addressed. (1) How do hailstones grow from embryos? Where are embryos most frequently located in a storm, and do different types of storms have different types of embryos? (2) How do hailstone growth and movement in a storm change as the storm’s updraft changes? (3) How do the different environments in which hailstorms form impact hail growth and production within? (4) How does the type of hail that reaches the surface change over the lifetime of a storm or in different environments? How do those different types of hail cause different damage to crops or buildings? (5) How can we improve ways to estimate hail characteristics from radar?
ICECHIP would use aircraft, unpiloted aerial systems, both fixed and mobile radars at different wavelengths, mobile sounding and radiometer systems, and a large suite of deployable surface hail collection and observation instrumentation to answer these questions.
